Gibson, Epiphone Adjustable Bridge for Guitars BLUE-G Planning & Manufacturing Adjustable Ceramic Saddle, Glazed Finish Plate for Ceramic Saddle (with protrusion) Reproduction Studs I purchased this new at a store a few years ago when the product was first launched. I installed it once on a vintage acoustic guitar to check it, then changed to a different one, and have been storing this one. I am selling it because I have no plans to use it. Thank you for looking.
